Add Modify Or Remove Variable Definitions In Configuration
These functions help in adding, modifying or removing variable definitions
in a configuration object obtained with ConfigFileOpen or
ConfigFileCreate. ConfigEditDefinition() will add the
definition if not existing.
ConfigEditDefinition(configuration, name, value, confirm = TRUE) ConfigRemoveDefinition(configuration, name)
configuration |
Configuration object obtained wit ConfigFileOpen() or ConfigFileCreate(). |
name |
Name of the variable to add/modify/remove. |
value |
Value to associate to the variable. |
confirm |
Flag to stipulate whether to ask for confirmation if the variable is being modified. Takes by default TRUE. |
A modified configuration object is returned.
